In agricultural production, a large amount of straws are thrown in the field after the fruits of crops such as wheat, soybeans, corn and the like are harvested. Through mechanical bundling or self-leaving field storage by farmers, solid impurities such as rubbles, blocky soil, iron wires, bolts, nuts and the like are often brought into the field storage by the field storage device in the processes, and the solid impurities cannot be effectively separated, so that the solid impurities are wrapped in the straws and are brought to a straw storage point. Originally, the straw is separated well in the process of crushing, but practice shows that the straw is crushed in the process, and is influenced by small straw density, large ash content and easy wrapping and lapping, and solid impurities are not easy to separate out. And the straw after smashing can directly be carried to the pyrolysis oven and handle, and the biomass straw charcoal of output after the pyrolysis is together with these impurity along with mechanical power output, cool down to the rubbing crusher smashes, causes rubbing crusher screen cloth, crushing dish to damage, has increased maintenance frequency and operation cost.
